David Vitter for Senate: What’s in it for the Radiologists?

According to the latest available public opinion poll, Republican David Vitter is 18 points ahead of conservative Democrat Charlie Melancon in the Louisiana Senate race, and with Melancon’s fundraising at half of Vitter’s he doesn’t seem liable to catch up. So why, according to the latest reports by the FEC, is the American College of Radiology jumping in today with $38,800 in independent spending on pro-Vitter internet advertisements? This comes on top of $15,000 in PAC contributions to Vitter from the American College of Radiology during the 2009-2010 election season.
